How could discussion end or talk be measured, if every answer is answered by another question? …To refute every contrary, headstrong, thoughtless, unmeasured word that contradicts our argument: You see it would be endless and miserable and fruitless. (Augustine, City of God, II)

One good thing from a better supply of covid tests: Incidence estimates, including asymptomatics—a big question mark now. Some headlines call for "massive testing" to solve this. What we need is the medical equivalent of a poll. elections : polls :: infections : random tests.

Recent news bayareane.ws/3dJ0422 has park authorities threatening closures after social distancing fails. With full respect to hard-working rangers and cops: Parks are efficient mental health clinics. Herd cats there, or they will go somewhere worse. Don't close the parks.

The restriction against statics in inner classes was lifted in Java 16. One effect is to allow the equivalent of a block-local static variable into any expression context in Java. This in turn allows code shapes previously available only via indy/condy. cr.openjdk.java.net/~jrose/jls/Fun…

How are Java types like Gilligan's Isle? Glad you asked: cr.openjdk.java.net/~jrose/values/…

Reading about the Joe robo-Rogan demo today, I think AAI will be a thing: Adversarial Artificial Intelligence. A well-taught robot ally can cheaply put down one’s foe, in whatever conflict. After figuring out how to be their own Darwinian principals, they will remember it all.

Quick talk at JVMLS on auto statics, computed constants, and inline constants. cr.openjdk.org/~jrose/leyden/…

I think that I shall never see Type inference which pleases me, Nor inference of nullity: Such inference is poetry.
